Not bad for your first event I think. Take note that several of these are underexposed... particularly the ones with snow. You probably know why but if not, I'm willing to bet you could figure it out quickly. The good news is that because you have the RAW files, you can fix this quite easily at the cost of introducing a bit of noise (which can also be controlled with the raw convertor).
I've found that processing RAW files and editing is something that takes practice and evolves over time, just like other aspects of photography. Fortunately, unlike other aspects of photography, you can take a 'redo' later on down the road once you have learned more. I've found that some shots that I processed when I first started were able to be improved dramatically with a different way of processing them.
