It's not that odd of a request and I'm sure we will all do what we can to help you out with this.

I haven't been here for long enough to learn everyone's style but there are 3 people I would check first based on what I have seen: Devin Night, Steel General and Xyll. The texture of the walls looks like what I remember seeing from them and I know Devin Night has done some packs for maptool so I would start with him.

Hope that helps but if not I'm sure someone else will be along here shortly.
