The only bit that springs out at me is the se gap.

Will

"play" appears to be kerned tighter than "house". At the very least the kerning on both sides of 'o' looks a bit loose.

My first impression was that the mark is too close to the P. It's the edge of the roof that comes too close; have you tried slightly tilting the house on it's axis to the left? Just enough so the gutter doesn't butt against the P's serif.

Oh, and what font is that? I can't place it. It's nice.

The font is Nexus Mix Bold.

Thanks for the critique guys, I'll revise it and post it again.
