1st one is good but the rest arent too special

fist one good everything is good in it the second one the pic needs to be blended more and the last just don't like what or how you have done it

[silenced]

1. Make them smaller 350 x 120 MAX(around there)
2. blend the render
3. give the bg some more depth
4. get text to fit the sig.
5. keep at it, you will get better.
