It´s great that youre patient=) I could never strip a model and paint it over, I can barely finish a model!

One of my best tips would be to read up on blogs and articles.
http://massivevoodoo.blogspot.se/ Has lots of awesome articles and tutorials from some of the top painters in germany.
http://www.juliencasses.com/ Is one of the top painters out there, defenately, some good tips and great inspiration.
Search around on CMON and other forums and find inspiration for your painting, look for different techniques like nmm, tmm, osl and so on, google for tutorials and try to copy them. With your patience, failiure shouldnt be a problem, just try time and time again=)
Try not to get stuck in ruts, try different things, look for stuff outside the GW field and style of painting, even outside the hobby that can inspire you! Also try things that are a bit out of your comfort zone, build bases and scenes up for your minis.
After 2 months, that mini looks great, especially if you got there on your own. If you want some tips on a new technique, I´d gladly try and help you, just send me a pm=)
Seeking help and advice from more experienced painters is a great way of learning, so is spending more time on a sigle mini, hurrying through regiments without trying harder wont improve your skills a single bit. this hobby may be the only where practice doesnt always make perfect, at least without some kind of guidance!
Best of luck
