You're one lucky dog to be so close to YNP! For me, it's a heckuva long drive for a day but one I've done more times than I care to mention. I too think some of the pics look a bit soft. But I really like no. 7.
A few comments about shooting in the park: Looks like these were taken during mid to late afternoon. Since you're so close, get out there for sunrise or sunset if you haven't already. That's when you get the best range of colors on granite, waterfalls, etc. And if you're not using one already, slap a polarizer on your lens. Your greens will be much improved over the greens in the tunnel view pics.
Please shoot and post more from this wonderful place.
