He will love it and won't notice the circle. Besides it not a glaring irregularity. Well done.

I think its just fine! Great design!

I like it just as it is,

I'm sure he will love it, it looks great to me.

I had to go back and see what you thought was wrong. From my experience it is only noticeable to you and you know what they ......."fiddlers are stuffer uppers" or worse!!!!!!!!

I didn't even notice until I read your comments! I think he will love this!!

Doesn't look bad to me, and I doubt he would even notice it. If he does just say you did it that way to give it eye appeal.

I like it very much. Surrounded it with some simple blocks in various colors (gray, rust--maybe churn dash) and I think it will be wonderful.
