yes and no. I'm to lazy to explain, but do yourself a favor and download adobe trial or somethin
Yes it would work, but NOONE would recommend it. the lack of tools is horrendous. as he said you should get an adobe photoshop trial or a psp 7.0 trial.
you can use paint. you can even acchieve great quality with it. but you'll have to work pixel per pixel to do it... wich would take you... i dunno... aboyt one year to finish one skin xD
