I think I speak for most "Artist" as I write this blog entry, we DO not enjoy just doing your eyes!
Picture having your car vacuumed, shampooed, and having all the interior polished as if it was right off the the assembly line. Then, picture the exterior chipped, nicked, dirty, and the tires drug through the mud. It doesn't make much sense does it? Well, that is exactly what you are asking when you want someone who does make up for a living and has a passion for a perfect finished look to "Just do your eyes." Your skin is the foundation or the exterior, and if you think you don't have any blemishes or an uneven skin, you are probably 3yrs old, because that's the last time you went without the environment affecting your skin. So, next time you ask a professional artist to do your make up, let them do what they have worked so hard learning to do!
