I think the chick is good looking.
The sig however, It doesn't have an eye catching attribute which is not good, as signatures have a wow factor.
But you're a beginner and everyone's been there before.
I think thata the text was a bad choice and has lowereds the standard of the sig even more.
Flow isn't too bad, but I would consider adding a C4D to add more colour and flow.
Good luck.
