#1 is promising. Others have already pointed out some of the main things about it, but I'd add that his posture seems odd to me. The way he is very slightly leaned forward, with the head tilted slightly down and the left arm extending out of the photo makes it look like he is either taking a "selfie" or about to lunge at you and your camera. Get your subject to sit up a bit straighter, and then shoot either straight at them or very slightly lower than they are; I think you were actually TOO low here, personally. (Although, I think that's a very individualized decision--but just be aware that the ANGLE from which you shoot a person can totally change the image).
The second one: Yes, you overdid the vibrance and clarity, and either overdid upping the saturation, or need to actually DEsaturate a little. I find with extremely colorful flowers, especially orange and red ones, I actually need to desaturate them a little to keep the color from overwhelming the details.
But the REAL problem with that shot is that it's just tough to get a truly interesting composition pointed straight-on at a flower. It ends up just being an ID kind of shot. Yep, that's a flower all right. Look for different perspectives, interesting angles, when shooting flowers.
