I agree with AJ above. Try some Vallejo paints - and this is coming from a die-hard Tamiya acrylic user (and yes, we've had our disagreements about Tamiya paints over the years).
There is much to be said for tried and proven methods, but at the same time, one shouldn't reject an idea or product because it's unfamiliar.
Rather than waiting two days for Humbrol enamels to dry, Vallejo acrylics can be layered in an hour or less, without lifting underlying coats. They can be mixed to almost any level of opacity with nothing more than water. They do like a nice flat primer coat to stick to, but this can be any flat paint of your choice.
I also agree about the brushes - spend a bit more and get some quality brushes. They may be more expensive initially, but if you take good care of them, they will last for many years. For 1/35 scale figures, I'd suggest a size 2, size 0 and a size 2/0 round, pointed brushes. If you can, select each one individually - examine the point, that's what you're paying for. Don't take brushes with frayed or stray bristles, or a misshaped point. The point should be as perfectly conical as possible.
And, as suggested above, practice.
