Welcome to OPF, Eric. These images are quite an introduction!!
Both are well executed, with great detail and sharpness. Very little to critique.
Generally speaking, it's best to post a single image per thread, providing details on how the shot was obtained (in terms of gear, settings, any particular post-processing, etc.), the circumstances, location, etc.
In addition, if there are any specific issues you want addressed in the post, it's very helpful to mention them (e.g. how could I have done this or that better or different, questions about composition, or whatever you want input on).
Excellent images!
