Keep it up! Looking forward to seeing more!
It's great to notice your own improvement, yes?
Some (maybe unwanted?) advice, to stave off getting bored of painting tons of little ones, I tend to have 1 big bug on the go as well. Just to break the monotony.
I'm sure you are starting to get confidence enough to give the big guy a crack.
Dont be afraid to drop the earlier bugs in Isopropyl alcohol (or your chosen stripping method) and start again, unless you want to keep them as a reminder of your beginnings.
