Yes, the eyes are much improved, but the left pupil (his left, not ours ... Our right) could maybe be scootched over a little more.
And WOW I'm impressed that's all done with MS Paint!!! I barely ever touch the thing myself, but it is a very good tool for people learning the pixelling ropes, since you can't use the blur or shadow tools or any filters ... Which are very tempting to new pixellers.
I use Paint Shop Pro 9, myself. The last one Jasc produced before Corel swooped in and messed it up. Sure, they added more features, but they dumbed it down and added too many workarounds.
A lot of people use Photoshop but I have a harder time with it for pixelling and small-scale images. There are a lot of workarounds, episodes of menu-surfing, and the zoom functions are a lot more idiotic, which are hugely important when dealing in small details.
Some people'll probably shoot me down there, so in closing on that I'd like to say that the above statement is preference-based and I am biased since I initially learned to make graphics on PSP. I do use Photoshop at work, though. Both programs are great, but PSP (I think) is better for small stuff.
If you can't find PSP9, try Paint.net (

You won't be able to create truly smooth lines in MS Paint because Paint is incapable of drawing anti-aliasing or feathering.
Another alternative to scanning and drawing on the comp is Adobe Illustrator. Ink your drawings, scan them, import them into Illustrator, and use the Live Trace function. It coverts your drawing to Vectors, enabling you to resize it as you like without quality loss, and every line will be crisp and smooth. Also filling it with paint is 10x easier.
The same effect can be done with Flash, and easier on the filling side, however it doesn't have a Live Trace function.
