I like the layout in terms of use of space and feels really compact otherwise if you want to achieve a RMC coaster you will probably need to rework all the layout. Try to use pictures and videos to have an idea of the shape of the hills and turn at a RMC coaster. I also suggest you to think outside the box and don't try to be so repetitive with so many overbanked turn. Also try to check the G forces in every element of your coaster. Practice is the key!
I think the layout looks much too complex. If you want an RMC feel, simplify it a little, especially the second pic. Also, you might wanna squeeze more airtime into the layout, especially ejector.
