Big amateur with big issue for your review

[Zakd]

Like I said, I'm big amateur and just entering in this beautiful field of photography.
There are two photos that I did last days and would like some help about this conversions. Specially about the second one. I did not managed to obtain good sepia look(some help over sepia conversion would be appriciated) and that is why would like to have all kind of comments as a help.
I was using Photoshop CS. Conversions I did because the original color was not good eather so sometime conversions can help.
Thanks
