First ever Mahogany? picture frame

So my friend brought this cast bronze picture to me and asked if i could make a frame for it because he bought it without any. To be honest with you i have never done anything like it before and I only started my woodworking adventure this year mainly with chopping boards so I thought I’ll give it a go… I hade this piece of I think mahogany and i thought that grain will look lovely on the frame when oiled because I have experienced that on a chopping board before (will post soon). I cross cut it and then thought about the profile of it… after few test pieces and playing with angles on my rubbish Makita MLT100 I ended up with what is on picture 5. then routed out a bit deeper groove to clean the left overs from ripping it and started sanding it down… I made myself a 45 degree angle jig before but that was the first time i had to make a frame and it turned out that my jig is not actually 90 degrees… Anyway after adjusting it and giving another go I ended up with fairly square frame…
glued it up with Titebond III and sanded the joints a bit more… Finally treated it with a mix of mineral oil and beeswax and here it is. My first ever picture frame !
I think that it turned out pretty good but I will leave it to you guys to judge… any criticism/advice is more than welcome.
