Found this among the drawings from the file recently found in my library. I remember I drew it in summer, while vacationing around the country in 2002, exploring caves with my colleagues from the speleological club. Whenever we passed something interesting, we would stop for a while and visit, then moving on to the next location of the cave on the list. So, I didn't have much time to sit and draw properly, mainly doing simple sketches to have as future reference for paintings or ink drawings.
