I also bought the nyx orange concealer whe I could not get the orange corrector from MAC - I like it. It takes a little work to smooth it out but for $6-ish, it's a good substitute.
I like the Graftobian palette - it's just the same product as the HD Creme foundation, but in portable palettes with multiple colors. I love how creamy it is, it doesn't feel like anything on the face and a little goes a long way. When I use for foundation I use a wet sponge, squeezed out to apply and buff with a Sonia Kashuk brush (the synthetic one for creamy products) and set with powder (I am oily). I use the darker colors to contour with the Kashuk brush (obvs before powder). I find that creme contour is better for me.
