3D scketch (again...)

 Do you think we can consider this one as a scketch? As with pencil I began to mold plastiline directly without any preparative and than I added some materials as drawing and something will be taken away;  I am very enjoied for this job and I get money too!
They are part of a project made for blind people (or partially sighted) and I am really very happy to partecipate...

 Finished, ready for the mould

Sand Martin - Maria Elena ferrari

This watercolour is the sketch of a river bank where the Sand Martin (Riparia riparia) nests, this little swallow breeds colonially and dig your nests in tunnels. In spring they arrive on our rivers from Africa wintering quarter. They need to find vertical river bank to erosion and a layer of silt and sand in which their dig galleries. You could find maybe a few hundred up to 6,000 nests! Unfortunately where I live are becoming fewer because of the river systems that no longer offers available habitats, sometimes nesting in gravel pits or sand, replacing the banks river I'm love this small animal (the subject of my thesis, 15 years ago!!), but is not easy to paint, due to flights acrobatic, better when they looking out the nest!!
