I experimented with lineless art. it was for the Pony part of the art within this piece : fireheartdraws.deviantart.com/… I will experiment with it some more, but if all goes well it will become my new primary style. As for how to go about doing it ? In my mind, its all about the shading, and lighting. It provides the contrast between the different angles, and if done right it will really give the piece realistic depth. Look at this artwork for example, made by another good friend of mine ( Julie ) obpony.deviantart.com/art/Derp… You can clearly see how she uses lighting, and shading to create the detail of the artwork, without the need of lines.To watch it in action, check out her Youtube channel here for Speed paints : www.youtube.com/channel/UCmMtm… Lineless art is definitely worth trying out to see if its something you enjoy XD
