Let me start by saying it's a very nice piece! I love the look of the canary wood!! I've never seen it before but will be on the lookout for it now!!
From a critique perspective I have the following personal observations:
The mahogany base doesn't quite flow from a color/grain perspective. The canary has a strong grain pattern of browns and creams. The mahogany has the red tint without any grain pattern (as least compared to the canary!). For me I think it's more the colors than the grain pattern. Maybe as the mahogany darkens over time the two color patterns will be contrasting enough to look even better! The bottom shelf is extremely functional but a bit plain. The pattern you have above is very bold and maybe having some reflection of that on the shelf could really add impact? On the other side of that equation is doing that type of change might have made it look too busy and the shelf less functional? I don't honestly think it's in any way bad/wrong/not right - just something to consider (assuming you hadn't!).
Still, a very nice piece and you should be very proud of the work! Clearly it will become a family heirloom for a very lucky person and family!
