Seems like my photo wasnt uploaded so i will post it one more time. Here
. So back to critque. Using ruler if u cant draw straight lines is a good idea, althou I'd suggest practicing those anyway, because this will allow you to get faster later. However blending seems nice, some spots not always needs to be blended or at leasr not that much. The noseseems little bit too much blende. We should be able to tell where the top of the nose is. Look up to the day 3rd and to the planes one more time. You should be able to fix this quite easily. Also look up for some ears because they are in mess. After this i'd suggest changing technique from charcoal to pencil or digital if u are able to. Charcoal is nice in the beginnig but now after this huge progress u made it will be time to focus little bit on details. Remember thou aproach it it same way as charcoal from general stuff to detail. It is very important cuz u might lose youself somwhere in the process. Good work and good luck with next day
