What is the size of your table?
If the red line is your elevated line, the ramp up is going to be pretty steep. If you can make the green line go down in elevation that could give the red line more clearance and make its ramp less steep.
Or you could remove the siding at the bottom of the diagram and have the ramp go around to outer edge of the layout. This way the red line ramp will never have to cross over the green line and the ramp can be less steep.
Building a layout for the first time is a trial an error process. What looks great on paper may not work on the actual layout. If you go with this plan as-is you may find that some trains will have a tough time going up the grade. Or even worse, trains will go too fast down the grade and derail at the curve.
Dont make anything permanent until you have tested the trains on the track. Then make adjustments to make train operation smooth and easy.
