Thank you guys and girls, for the nice comments.
Abe Babe, I don't use Photoshop, although I reckon it is more powerfull than the
GIMP. However. the GIMP is completely free, and there is an increasingly set of diferent plugins avilable in the GIMP site. After reading what you said about learning, I decided to write a few short tutorials, showing the basics of the steps I use to make pictures. coming soon!
Mudokon101, I lke to make sketches with pens and scan them to continue the work in the computer, but in this case I made both pictures completely with the mouse and the software I mentioned. When I started the first one I didn't have a fishman in mind. I started with a basic shape, intending to make a man's face. I was having probles making his nose, so I ripped it off. I started to mix colors and got the grey tone of his skin. So, the idea of making a gishman came to me. I added the big ears, and the Greek-like elm. The ear-rings seemed to be a nice touch. It added character to the warrior.
In second one, I was playing with shapes again, and in the middle of the process, I just got the cool "fur" effect. So, I decided to make a creature with that cool affect. A lion-like creature came fisrt, but then I decide to make a wolf like creature, and I was pretty much pleased with the resulting head. My idea was to add a right arm just like you can see in the first model of th eearly version. I wanted to show his claws

. But I got too lazy after all the work. Maybe I'll add it in the future.
And for everyone who wants to start editing pictures with a very decent tool, and totally FREE, try the GIMP software. Go to
this site and dowload the windows version. I'm sure you're gonna enjoy it. I know that Midlesboogie uses it, and after a brief period of adaptation, can use it very decently.
