Thanks everyone, I'm glad to hear you guys like my artwork.
About the other pictures, I stopped my work on them, I might get around to it later, but detailed pictures are really hard to do with paint... I'm currently soon going to get a tablet so I can draw real pictures (well technically this is real art but you know what I mean by that) and maybe even a scanner to share some of the pictures I drew in my sketch book. Don't rush me though guys, I'm only 14 and I don't get an allowance or a paycheck. I might post pictures kinda like the Mini Uzi now and then but not like my first picture, if I do I will surprise myself.
Wow, that's incredible, especially with only Paint. Think about what you could do if you had Illustrator/Photoshop. Coincidentally, there are alternatives for both; Inkscape for vector and GIMP for Photoshop. Google them if you want, they're both free downloads.
A vector is a line described by a path of coordinates and a formula. The advantage of using vector images is that resolution isn't fixed to zoom, meaning that zooming won't result in a loss of image quality. This is particularly important if you want to include parallax in your game/animation.
Awesome anime dude! That one is well...paint? Lol. That is hard to do, I can't make a good picture with this computer. [Except for Photo Shop, lol.] But, man, awesome! Good job.
