Raise that elbow or you won't have to worry about your fingers because left long enough, you'll induce tendon damage in the wrist that hurts so bad you eventually won't want to or be able to play again.

Most important in this stage, use proper fingering for the scales... it makes it easier.
The raised finger issue? It is going to work itself out. As you get more and more comfortable, you will naturally start to speed up more and more, and your fingers, all by themselves, will rise just the perfect amount to meet the needs of the speed you need to play that scale at.
BTW, so happy to see you working on scales, so many people just don't get the importance of scales and arpeggios and it does affect their growth.
If I may also suggest, as soon as you can, start the Hannon exercises start doing them all in the key of C, and later, go right for repeating those same exercises in all the other keys... you will thank yourself later when you start picking up more technically challenging pieces faster and easier.
Funny but true story... I cannot tell you how many times I got whacked across the tricep by a short baton and my teacher pretty much barking out an "UP... UP... raise that elbow!" at me... easily has to be in the hundreds of times, at least it felt like it! Sometimes the bruises from the last class weren't quite healed before he added another line!
