This model is an Ottoman design. And it is coming from Selçuklu. They are Turks. Their motives are very valuable and aesthetic. This motif have critical angle. Too difficult to find the right angle this motif. If you can't to be true angle, you have a unsuitable motif :( But I FOUND the true angles and I did a good job. If you work for modelling this motif, You must have a lot of time. You haven't got a lot of time. So, you must buy it.
