@zayedsakib once told me to start focusing on miniature art, where I can find enough room to improve the techniques of making tiny details. And I believe this theory as it costs more patience and concentration compared with blending colours on a big abstract canvas. So with those gelly roll pens, I made some boxes and started contrasting zentangle with floral art. The detailing could be done more precisely but as I'm a noob with this pen, it'll take little longer to gain mastery over this art form.
But still, as a beginner, I think it's a good start and the result is comparatively better than yesterday's! And if I can keep pace with the design, some beautiful pieces will come out, no doubt about that!
