Nice photos. You might want to consider UV treating the 50mm. Its seems to have a yellow cast that is common with thoriated lenses (if your lens is the 7-element variant). You can "clear" the lens by putting it under a bright light source. I use a Ikea LED lamp. It takes a day or two, but the images taken after are sharper and the white balance is better.

Here's a image of one lens that has been "cleared" and one that has not.

Thanks for the advice
