Got bored sitting in this blasted hotel room (I've been traveling on business quite a bit lately).  This crappy netbook I'm using doesn't have many other uses, so I loaded Gimp on it, stole a few graphic files from the web, manipulated them a bit (try THAT with a half size keyboard and an overly sensitive touch pad!), and VOILA!, my first attempt at a sig!  I know, I know, it's lousy, but I like it anyway!

Josarthu

i like it
like the grandpa...but maybe put him more to the left side. between the text. we can see him better then. it looks like he would crouch away ,down there in the edge ,hehe
if you put him more to the left and a bit higher ,it would give him a pop out effect "here i am , old and still alive^^" apposite to your text "not so hard to kill"

Josarthu...nice work!  Good for you for giving it a shot!

Now with that said, check out the tutorials that Heraclas has made and some of the other available here in the sig gallery.  Then you only have two other things to do:
1. Keep trying...practice is what makes you great!
2. Don't be afraid of input!  Listening to the views of others and trying what they suggest will lead down new paths that may suit you!

Keep trying it, have fun!

Nice job!

OK, second attempt.  I like this one MUCH better, and will probably go with it.
