Digital Art which should i use?

i will probably use garra but thats cuz hes my favorite. so which 1 should be my sig?



i posted thes in the order i made them, but i only spent bout 10 minutes on clouds cuz i was playing a game too.:D

 

I think the first one because it looks the nicest, as if you spent the most time on it.

 

first one it is and yes i did spend most time on it but i was still testing the software and brushes i just downloaded and had to see them all so its my first sig ever:)

 

Cool. Well, good job. Better than I could ever do.

 

thanks the only tips i can offer are try random things and if they dont look good just undo it, something i am very good at (even in math i can tell if somethings wrong if it doesnt look right)
but now i feel like an idiot cuz i cant figure out how to get it in my sig it says its invalid file type?

nevermind it works now
