Very nice EG , you definately have an individual style going there mate.
Can I just make a couple of suggestions for you here ?
Number 1 ,,,,the far mountain range , next time if you have a damp piece of cotton pad or tissue paper handy before it dries , just use it to soften away the hard edge of the top of the mountains.
Number 2 ,,,,, you have allready noted the prob with the foreground rock , I would suggest it really needs to be a whole lot darker to distance it more from the rock in the middle ,, mabe even at this stage a quick one stroke wash of very heavy mix of french ultramarine over it ,, but you cannot faff with it or it will ruin it , just a one stroke operation.
I think you are using green from a tube ?? dont know if you are but I mix mine from black / paynes grey + cad yellow to get a more natural green .
Please dont take anything I say as criticism as I cannot do any better ,, I am just offering a different viewpoint and would welcome anyone to do the same to anything I put up here .
I love the feeling of the heat you have generated in this pic very clever .
Your paintings are bright + happy looking ,, I guess it reveals the way you are .
Looking forward to your adventures in acrylic , I haven't a clue never been there
