But yes add some shading to the left of the ball.
Everyone's a critic, keep doing what you're doing everyone has their own style of drawing. Sure those that critique you on your work is ok, but you should'nt change what you do if you are comfortable with it, i like it and not that many people can do a shadow as detailed as the one you did chief, hope to see more work from you ;)
A very nice picture indeed but here's some critique if you don't mind.
-Shading needs to added to the left off the ball to indicate an added light source.
-Shadow is on the wrong side with the sun(I think that's the sun)
-The arms seem a bit off because they go straight instead of curve a bit towards the middle.
-The stomach really shouldn't be curved because it looks like shes sucking it in which looks just a tad awkward.
I guess what aoisgd is saying that you give off a feel that your a young artist, which may or may not be true
But from aside that and some others you did a really nice job. Keep it up.
it's a good drawing and stuff but i think you must make a better work with the eyes because (it's just an opinion) are a little like the kind of eyes who a 10 years old kid who likes anime can do ...you have the potential to do it better
