Very good drawing needs a lot of dark background to bring out the face it will help with the photo which is showing over exposer. Don't write on the portrait it makes it look amateur and child like. Signature only, date and who on the back . Tip for the future You have excellent little with no dark balance between try more darker Pencils they go from B to B9 darking in tone. Don't lose the very good eyes. Better to have no shading on the face or a hint of shade a hint is done with powder or graphite dust you can make you own by collecting old pencil removing the lead then crushing these lead pieces until very fin then using either your finger or a tissue lightly dusting on to the areas you wish to shade.
