Regardless of the intended character... The form is good, basic, but good. In the future, I'd suggest adding আরো depth. আরো texture overall, shading, specific detail, and highlighting -- specifically in the hair. Make it as realistic as possible, and most of all: KEEP AT IT!
My drawings used to look a lot like this, and trust me, আপনি will improve if আপনি keep going!
আপনি can do this too, that's all I'm saying. Because I know how discouraged artists can feel.
The সামগ্রিক image is pretty good, but in my opinion the bubble sizes could be আরো varied and the blue overlay could be a bit আরো dimensional, too (I like the effect it gives, but like, perhaps in a few আরো different shades of blue, does that make any sense??)
