Whew! I simply did not have the time I needed to complete this in one day, but it is now finished!
First off, let me just say that Rainbow Dash has always been my least favorite of the main six ponys in MLP:FiM... But I'm not going to lie, I gained a LOT of respect for her from the last episode when she got Tank as a pet. Tank is just freakin' awesome and I thought he was the coolest turtle and I couldn't help but root for him since he was trying to impress Rainbow Dash with sunglasses at Fluttershy's. And I was just glad to see Rainbow Dash not going for the typical "This is what's coolest" deal, and I felt the overall episode to be very touching.
So I immediately decided that I was going to draw an image of Rainbow Dash and Tank going for another go in Ghastly Gorge during the sunset as Quarray Eels try taking some snaps at them! While rock and canyons still give me a good deal of trouble in terms of rendering, I'm glad with the way this one turned out!
