Since you are asking about your technique I don't think the powers to be will say something about this thread (aka, Nathan). We normally post pics in the gallery. Any pics other then a visual reference.
That being stated, you are doing just fine. I don't exactly know how much you have painted in the past. I would not put a paint line thru a kill spot. The first two is fine and look nice but I would put a gill plate, kill spot, fins or something to jazz them up a little. See that's the problem, that's my taste. Your technique is fine for someone beginning.
To me for looking at pics with clear coates/top coating I have trouble seeing details. These coats kinda makes paint schemes blend together, if that make sense. Paint work to me without clears can be seen better. It's a fine line between just enough details and over doing to me.
You are doing fine.
Just my,
Dale
