ENB is DX9 only, so is useless here.
ENB is a DX9 injector which you can tweak DX9 games, its very popular since GTAIV, it really improves the DX9 games.
It not only let you adjust games effects but also add new ones, for example, it let you tweak TES Skyrim HDR and it add SSAO too, very useful with old games too.

I really like those screenshots, you did a good job stimulating the lighting adding yellow, looks really good.
Shame that this dont work with SMAA
