Colouring techniques

I am having troubles with my colouring....I try so hard lol but it never looks like the ones I see coloured on the blogs. I've tried looking up U Tube but don't seem to find anything overly helpful on there.

Anyone else got some good suggestions?

Cheers

PS may finally get my new oven in on the weekend....AND our air con broke after yesterdays 41 degree heats :( AND I am positive we have some kind of spirit in our house (no I'm not crazy!) and I did a little test last night...yep something isn't right here....SO I called a lady who is going to do a house extract (from her house) and we'll see how that goes! (am grateful she is free)
