Let's try this type of problem: I give you the full solution - key move and all variations, and you try to compose the problem.

Mate in 2.
solution:
1.Rh4! Threat: 2.Nb3#.
1...Nd3 2.Rxc2#
1...Ng4 2.Bd6#
1...g4 or gxh4 2.Qe3#
1...Bd3 2.Nb7#
1...Be4 2.Qd6#
1...Nd5 2.Rxd5#

So far, these are certain:
Black has pawn on g5, Bishop on g6, Knight at e5, and King at c5
White has Rook at d2, Q at h6

EDIT:
Okay here is what I am currently looking at (position after 1.Rh4!)
Invalid FEN inserted - 3N4/3Pnp2/6bQ/P1k1n1p1/K6R/8B1pR3B/2N5

What I am not sure about is whether the bishop should be on g3 or h2, and where the rook at h4 should be coming from.

White's position is too strong. If the h4 Rook came from d4, White could have played 1.Nb3#, and if it was from another square, 1.Bg1# works.

Only minor adjustments to ilywrin's position were needed to get the solution.
