Australian Grass Tree Explosion Box

I designed this Australian Grass Tree Explosion box in honour of the beautiful grass trees that we have seen around the north west of Australia in particular and the need to make some boxes that might appeal to a male recipient. In the middle I have added a gum tree and 2 stamped gum trees cut and erected as a free standing pop up. The background mountains, sky and ground has been sponged.

I used Archival Jet Black ink to stamp the trees and sponge the mountains and ground with a hint of brown and yellow inks for the middle ground and blue for the sky. The masks for stamping were free torn post it notes with 'peaks & valleys' torn as I went.
All these were done on glossy white photo paper which were then matted on orange card stock then black before laying the whole onto bright yellow card stock. I cut the corners into a diagonal cut for a change to make it quite bright. For contrast I made the lid from the same orange card as the layer. I just couldn’t help myself, I just had to add a few dancing butterflies.

The trees are all Print Block stamps from eons ago. The cards are from my stash which could be from anywhere. Sorry most of my papers & cardstock were just bought and kept with out any reference to who & where they came from.
Do you think this is more suitable for a male? Or is it too bright?
