Art Improvements

Hello! I'm currently working on my art and improving it. Sure, it seems good now, and I try to make it realistic, but really, its not. I am going to focus on making my art more realistic, and improve how I draw cats... Especially with eyes, I'm horrible at drawing realistic eyes. I will not be posting art as frequently until it starts to improve. Until then, I'm going to really start observing other's art, and hopefully get some inspiration. It also doesn't help that I use my tablet to draw. I really want to get Paint Tool SAI for my computer, but of course, my parents won't let me. Looks like I'm going to have to wait until I'm allowed to get my own computer in 2 or 3 years. But anyways, I'm open for suggestions to help me improve, because in the past year, my art has stayed the same, which is really annoying, considering I started getting into art 4 years ago.

Thanks!
