My Gorjuss Gilrie

Here is my first attempt at using my new Gorjuss girl stamp. I dont think my colouring in is very good, I need better pens (I actually used pencils this time as I was desperate to try it). Im not sure who ill be giving this card to and for what occasion so I may add a Happy Birthday to the front at a later date, or just leave it blank. Any tips or critacism would be greatly appreciated. id like to know where im going wrong, or how I could improve it before making anynore. ta muchly x
