Yes I would say that is a strong sativa strain compared to most indoor grows. prolly not all sativa but alot more sativa than most strains bred for indoor grows. & I have to say it's beautiful! I absolutely love that first pic you posted (the top-down perspective). That sativa high is sure to be wonderful, i bet that smoke has an epic high. Give yourself a big pat on the back, looks like you've gone for quality instead of quantity & being your first grow I think you've done a great job & I can only imagine how happy & proud you are feeling.
