Right now your garage doors are the prominent feature of your home because they are in front of the rest of the house. You want to minimize this effect and make the front door the feature. I would paint the garage doors white so they blend in with the siding. For the front entrance it would be ideal if at some point you could have an overhang built over the door. This would function as overhead protection for anyone standing at the door but also would add visual interest to the doorway making it more prominent. Once the garage doors are painted white, it would help make the front door stand out if the brick around it was also painted white. I would replace the door with something that has at least some glass, even just 2 small windows at the top of the door will look more inviting. I would also add some potted plants in the front entry area. Once the garage doors and the brick is painted white then you can paint the front door a color like red for instance and it will stand out. For the final touch, I would add an interesting door knocker. Hope this helps!
