I'll just say what I see.
The colours of this card stand out in stark contrast to those of the blackbird card. The greens are so yellowed, so new, they seem fresh, as they do in Spring. The bracken or ferns are lush and verdant. The oak around the edges of the card is sporting acorns, would they be fully-formed in the Spring? If not, perhaps the season is closer to Summer, however I really feel the invocation of Spring.
The sunlight on the hind (who is showing us her hind!) seems to be illuminating a small clearing or a path through the forest. There is a real warmth to the card, and a lovely stillness. Deer in general imply stillness and silence and serenity to me. Perhaps because without those elements present it is unlikely a deer would remain!
The light shining down as it is indicates to me a serene and treasured moment frozen in time, or taken out of time. To catch sight of a deer in the forest is to catch your breath in the hope that the balance of the moment will not be upset. In those moments (whether figurative or literal) I always feel that should I breathe, the scales will be tipped and something beautiful will be lost.
The stance of the hind also puts me in mind of vulnerability, something delicate and precious. White often stands for purity and seems an appropriate colour for her.
Just some thoughts to begin with. Perhaps more will folow.
