I'm not an artist. I don't make nice, cute, pretty pictures like everyone else magically, (That's how I think of it....when people draw, it's freakin' magick!) but I write. I write... alot. But today, I got on Sai, and tried to futiley draw, mostly and almost entirely using the curved lines and lines tools... and came up with a... kinda picture thing? I just want to know if it's considered... decent. And what I should do next to try and become...decent-er.

You made good use of the line tools, it looks smooth, very nice for a first try (right?). The style is cute, too - kind-of chibi-like, but not a chibi. Though, I'd suggest working on the hair, legs, and wings of the wand. For the hair, you're looking for consistency in shape, and line size. The wings are lumped, more hand like. The left knee is down too low for the position it is in, almost looking as if it is backwards and laying on the floor. With practice you could be really good at this style. :)

Stooooop! Don't use the line tool when you draw! It builds bad habits, since you get to move the lines around and fix your strokes, meaning that you'll never have to draw the line perfectly right the first time around. Then you'll have a very hard time learning how to draw lines properly, since you could always tweak them... If you want to build drawing skills, you should practice drawing lines with the Inkpen tool or something like that.

Also, tip: drawing bigger means you have more room for cleaning up mistakes.

With that out of the way:

• Your color choice is decent. Most beginners tend to have no color sense (cough me cough) and end up pasting saturated, contrasting colors all over the place that don't match at all. You didn't fall into the trap, which is great! You choose mostly warm colors, giving this picture a nice overall harmony.

• Anatomy is your biggest issue. Generally, no matter how pretty the colors are and how intricate the line art is, if the anatomy is off, a picture will look derpy. As a disclaimer, you should probably learn anatomy from official guides and studying from real-life, but nobody who draws for fun actually does that until they start becoming really serious about drawing, so my suggestion will be less realism-focused.

I'd suggest looking up anatomy guides on the internet or use references when you're drawing. I find eye-tracing to be especially useful. Eye-tracing is when you look at a picture and try to draw the same picture, without putting your paper over the picture (normal tracing). Eye-tracing is, of course, only for practice, and you generally don't want to post it on the internet, since the art is technically not yours, but it's very good practice. It develops your sense of proportions and where things go in relation to another. For eye-tracing, find pictures that are certified to be of good quality -- photos of real people are of course the best, anatomy-wise, but sometimes other people's drawings are good, too. If you don't have a sense for anatomy, I'd suggest looking up anatomy guides first so you know what to look for, then looking for refs.

When using other people's drawings as refs for practice, be careful. A lot of drawings, no matter the style, has wonky anatomy. Generally speaking, official art from anime, manga, cartoons, video games, and whatnot are usually good, since they have to pass through quality checks to get aired/published/funded, but some older art is really derpy and should be avoided. If you're trying to learn from anime/manga, just make sure you check up on different styles every now and then so you don't accidentally end up learning from bad art. So if you're, say, using an anime as a ref, make sure to switch to a different anime or a video game after a while. Also note that a lot of drawn art are stylized, so they can be wonky at times. This means you'll still have to check anatomy with pictures of real people every now and then.

Last but not least, make sure to have fun! If you don't like the style you're drawing in, switch to another one! Try things out and experiment. Art is supposed to be enjoyable.
