ok what am I doing wrong?

ok you clever stampers!! Why is it I stamp the image ok, but colouring it in...whatever I use sakuras, h2o, water colours it looks absolute rubbish!! I follow all the tuts which look soooooo easy but I still manage to turn out tat. As for cutting out...well Ive tried close to line with scissors, craft knife and leaving a small teeny weeny border and its still looks ****. Any help would be gratefully appreciated!!!!


Help...dont need the stress!!! LOL
