But seems that you are making things too blurry. Try using the hard brush or whatever its called. Also, i see there are some black line looking things there, i would suggest doing the sketch on an underlayer, then colouring on a higher level layer. Then hide the sketch layer, shade and highlight and work on details.
I have access to corel, and now thanks to you i have inspiration
